Potential cancer drug may offer new hope for asthma patients
A drug being tested to treat cancer could also help patients suffering from asthma, research has suggested.
Scientists at the University of Edinburgh found that the drug – R-Roscovitine – helps to kill certain immune cells which can exacerbate symptoms associated with asthma.
The findings could lead to an alternative way to treat asthma in patients who are resistant to steroids, which are commonly used in asthma treatments.
Researchers studied the effect that the drug had on immune cells known as eosinophils
Eosinophils, found in the lungs and airways, help the body fight off parasitic infection. However, too many uncontrolled eosinophils can damage other cells that line the lung, contributing to inflammatory conditions such as asthma.
Researchers found that use of the drug caused the eosinophil cells to undergo a form of cell death known as apoptosis, a natural process where unwanted cells are removed from the body.
Professor Adriano Rossi, of the Centre for Inflammation Research at the University of Edinburgh who directed the study, said: "Steroids are commonly used to treat asthma but can have unwanted side-effects, while some asthma patients are also resistant to steroid treatment. It may well be that use of a drug, such as R-Roscovitine, or one that works in a similar same way, could offer an alternative to steroids, or be used in conjunction with steroid treatment for asthma patients."

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
